Shandong police have rescued 37 infants after breaking up seven human trafficking gangs in the past two months, according to a China Central Television report.

A total of 103 suspects from the gangs have been detained for further investigation, said Xie Xinxi, director of the Jinan railway police department.

"The gangs sold the infants after they were born in underground delivery wards. An infant girl was sold for 60,000 yuan ($9,800) while a boy would bring 80,000 yuan," Xie was quoted as saying by CCTV.
